Gingrich Is 'At The End Of His Line' Says His Biggest Financial Supporter

Sheldon Adelson, the Las Vegas billionaire who along with his wife has used a superPAC to pour about $15 million worth of support behind Newt Gingrich's bid for the Republican presidential nomination, told reporters earlier this week that the former House speaker's campaign appears to be "at the end of his line."

Adelson told reporters he doesn't want Republican contender Rick Santorum "running my country" and that Mitt Romney is "not the bold decision maker that Newt Gingrich is." But Gingrich, he said, "mathematically can't get any where" near the number of delegates he would need to be the nominee. (NPR.org's "delegate tracker" is here.)

"Met secretly with GOP rival Mitt Romney on Saturday, according to a source close to the campaign, but the former House speaker says he has made no deal to end his bid for the GOP nomination.

"Mr. Gingrich, responding to questions from The Washington Times, did not deny the meeting, but explicitly said he hasn't been offered a position in a potential Romney administration in exchange for dropping out."

Gingrich also told the newspaper that "I plan to go all the way to Tampa," where the GOP holds its convention in August.

Wednesday, we learned that Gingrich was laying off about one-third of his campaign staff and hopes that a deadlocked convention will turn to him.
